Direct Memory Access

Controller for System

(SYS-DMAC)

(For All Products)

• 16 channels for PeriW domain (SYDM0)

• 32 channels for PeriE domain (SYDM1, 2)

• Address space: 4 GBytes on architecture

• Data transfer length: Byte, word (2 Bytes), longword (4 Bytes), 8 Bytes, 16 Bytes, 32 Bytes

and 64 Bytes

• Maximum number of transfer times: 16,777,215 times

• Transfer request:

Selectable from on-chip peripheral module request and auto request

• Bus mode:

Selectable from normal mode and slow mode

• Priority: Selectable from fixed channel priority mode and round-robin mode

• Interrupt request: Supports interrupt request to CPU at the end of data transfer

• Repeat function: Automatically resets the transfer source, destination, and count at the

end of DMA transfer (by descriptor function)

• Descriptor function (each channel) supported

• MMU (each channel) supported

• Channel bandwidth arbiter (each channel)
